YPF100 custom: differences between H and S according to Eng. Medri's charts May 3, 2021 13:05

The bending inertia diagrams of the racquets highlight the difference in the general behavior of the two frames. The S series has a general bending stiffness of 62 RA points compared to 70 RA points for the H series, but the key element to note is that the stiffness of the hoop is similar for both series, giving a full and very solid feel to both racquets.

The S series shows a more progressive and linear behavior, with stiffness progressively decreasing from the shaft to the racquet head, while the H series has a more aggressive behavior that differentiates the lower part from the upper part for a greater stiffness differential from the head to the handle.

The difference in character between the two racquets makes the H series more suitable for powerful hitters and players looking for pronounced spin, while the S series is for those who like to vary their shots and play with great feel, bearing in mind that both frames are designed for competitive play with a strong pro-stock spirit.
